OIL-PRESS MAT.

SPECIFICATION forming part of Letters Patent No. 758,573, dated April26, 1904.

Original application filed September 10, 1901, Serial No. 74,906.Divided and'this application filed June 26, 1902. Serial To all whom, itmay concern:

Be it known that I, ROBERT FRANZ WERK, a citizen of the United States,and a resident of New Orleans, in the parish of Orleans and State ofLouisiana, have invented new and useful Improvements in Oil-Press Mats,of which the following is afull, clear, and exact description.

This invention relates to oil-press mats; and the subjectmatter of thepresent application is a division of a prior application for LettersPatent filed by me on September 10, 1901, Serial No. 74,906.

In the present invention it is my purpose to produce a hair mat orfabric which shall be durable in service owing to a peculiar combinationof hair in different grades, and at the same time the mat is not liableto split or tear apart under the pressure of the seeds and thepress-plates; nor will its threads or strands unravel, and it is capableof being folded lengthwise upon itself without breaking. These ends aresecured by making warpthreads of soft pliable hair,.while theweftthreads are made of coarse stiff hair mixed with soft pliable hair.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both the figures.

Figure 1 is a plan view of an oil-press mat constructed inaccordance-"with my invention, and Fig. 2 is a longitudinalsectionthereof on the line 2 2 of Fig. 1 I

As shown by the drawings, the fabric or mat consists of longitudinalwarp threads or strands A and the weft threads or strands B, the samebeing interwoven together to produce a complete fabric or cloth. Thewarpthreads A in the present invention are made of soft pliable hair,the same being properly selected and arranged so as to be spun ortwisted together in order to produce a strand of the proper length andthickness. The weftthreads B, however, are made of hard, stiff, andcoarse hair mixed with soft pliable hair. The hairs are mixed in theproper proportion,

the pressure over the weft-threads.

and they are arranged in a manner to be spun (No model.)

or twisted together for the production of a strand having the'properlength and thickness. I prefer to make the weft-threads of greaterthickness than the warp-threads; but this increased thickness may not beobserved at all times in the manufacture of the mat when the latter ismade of hair having the qualities herein described. The warp-threads arearranged in parallel relation to extend longitudinally of the mat, whilethe weft-threads extend across the warp-threads. The two series ofthreads are interwoven together for the purpose of making thewarp-threads entirely conceal and protect the weft-threads. In practiceI prefer to make the warp-threads greatly exceed in number theweft-threads, and I may employ from live to eight times per square inchas many warp-threads as there are weftthreads, thereby making the warpprotect the weft to better advantage, because the seeds are preventedfrom passing through the warp and injuring the weft, and at the sametime the warp serves to more uniformly distribute The increasedthickness of the weft-threads imparts the desirable cushioning effect tothe warpthreads, as the warp is liable to cut into the weft-threads. 7

The improved mat possesses all the good drainage qualities, because Iemploy horse-' hair in its manufacture, and the durability of the mat issecured by the use of long animal hair combined together in differentgrades throughout the warp and the weft. The mat is comparatively freefrom any tendency to split lengthwise under the pressure of the seedsand the press-plate, and it can also be folded longitudinally withoutbreaking or giving way.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. An oil-press mat or cloth consisting ofwarp-threads and weft-threads made of long animal hair, saidWarp-threads being composed of soft, pliable hair, the warp-threads atthe middle of the mat being made of longer hair than the warp-threads atthe selvage, and the weft-threads made of hair of medium grade, theselvage of the mat being formed by said Warp-threads of soft, shortpliable hair.

2. An oil press cloth consisting of Warpthreads and weft-threads made oflong animal hair, said Warp-threads being 'composed exclusively of soft,pliable hair, the Warp-threads at the middle of the cloth being made oflonger hair than the Warp-threads at the selvage, and the weft-threadshaving hard, stiff and coarse IO hair mixed With soft, pliable hair, theselvage of the mat being formed by said Warp-threads of soft pliablehair.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
